Description

Placebo

The KCCQ is a patient-reported measure for patients with heart failure. It consists of 23 items, is comprised of 7 clinically relevant scales (Symptom Frequency, Burden and Stability, Physical and Social Limitation, Quality of Life, and Self-Efficacy), and yields 3 summary scores (Clinical Summary, Total Symptom, and Overall Summary Scores). Scores range between 0 and 100, with higher scores indicating better health status (eg, better functioning, quality of life, fewer symptoms). Number of participants with available data = 1106 and 1104 for each treatment group respectively, total = 2210.
